As we are announcing today MHD for F series, we would like to use this official thread to gather discussions, updates, user logs, dynos and videos. Community feedback has helped us shape the best tools and maps for E-series, so we're counting on everyone to repeat the same joint effort.

To get things started, here is the product description.

MHD Flasher F-Series (N55/S55/N13/B58)

The MHD tuning team is proud to present its latest product - the MHD Flasher for BMW F-Series. After two years of development, the wait is finally over! The MHD Flasher F-Series is a complete flash tuning app for your BMW. Unlike a piggyback module, it is capable of complete DME remapping while retaining all OEM safety mechanisms. This allows for maximum performance,maximum safety, and unrivaled drivability.
Several thousand customers worldwide have been enjoying the number one flash tuning tool for the E series N54 and N55 platforms (MHD Flasher N54 / N55 E-series) since 2015. Come join us now for the F-series launch and see what all the hype is about!

Product details:

Full OBD Flashing:
You can install MHD right at home and start tuning immediately! There is no need to remove and send out your DME for a costly “unlock.” Simply download the MHD Flasher F-Series app that connects via a K+DCAN cable to your Android device and your vehicle’s OBD-II port, start the app, and within 25 minutes the initial installation is complete. Further map changes are much faster - only 3 minutes! You can revert your vehicle to the factory OEM flash at any point, and no initial backup is necessary.

Stage 1, Stage 2 und E85 OTS (Off The Shelf) Maps by PureBoost:
We offer a wide selection of OTS maps for the N55 PWG, N55 EWG, S55, B58 and N13 engines suitable for many different vehicle modifications and octane levels. They have been extensively road and dyno tested, just flash and go!:

As an alternative to built-in maps, many local and remote tuners can provide advanced custom mapping for those who have more extensive modifications or unique performance / customization needs.

Monitoring and Logging Module:
Monitor your engine behavior to make sure it is running perfectly using a configurable and very responsive gauge layout. 50+ engine parameters are available at a glance! Activate the logging mode to save the data to a standard CSV file for later analysis using the built in log viewer. Additionally, we will happily provide free logs analysis.

FAQ:Q: Can I test the connection before making a purchase?A: Yes, simply tap the MHD Store button. The ECU connection is checked before displaying available purchases.

Q: Can I tune different cars with one license?A:Each vehicle has its own unique license (VIN and google account locked), tuning a different car requires purchasing a new license.

Q: Can I tune multiple cars with one google play account?A: Yes, you can purchase multiple licenses with one google play account.

Q: Can I transfer my licenses?A: Licenses are personal and stored by google along the account used at purchase time. The purchases are tied by google to the first account and can’t be transferred to a new google account.

Q: Does my Android device need to be permanently plugged to the OBD port?A: No. Once a flash is performed you can unplug your device.

Q: Do I need to purchase a new license each time I flash a map?A: No, you can reflash as many times as needed. MHD maps updates are free.

Q: Is a battery charger required?A: It is highly recommended for long flashes (install, uninstall). A healthy battery will handle short flashes (map changes) fine but the use of a battery charger remains recommended.

Q: How do I take good data logs?A: Press the Monitor (auto log) button, stabilize around 2500 rpm / 3rd gear (4th on 8 speed AT) with DSC fully off. Mash the pedal, shift at 6500 and 2-3s after the shift into 4 release the throttle. Slow down, stop the monitor. If you want us to review your log, then upload the log to www.datazap.me and send us the link.

We will start a closed beta period from 1-1-2018. Users willing to actively participate and provide datalogs can drop us an email right now. You can get $5.99 off a bimmergeek cable with the oupon "MHD".

Expected closed beta period is 4-6 weeks, after which we will go public.

So there are no M2-specific maps, correct? How does that work since the M2 is in a higher state of tune than your run-of-the-mill N55 from 2013-2016? Looks like Stage 2 or Stage 2+ are the pump fuel options for this platform.

If there aren't specific M2 maps, then that's a big product differentiation from other current and upcoming flash options. Is there not enough economy of scale to worth the effort for MHD at their price point?

Martial, when unlocking via OBD can you obtain a full copy of the oem file? From speaking with other OBD unlock options tamper codes, flash counter and flash back to stock can be taken care of. However in the scenario where the car is flashed back to stock for a dealer visit and if they perform a software update the tamper and tuner codes will appear. Is this the case with your solution as well?

There will only be a stage 2 and 2+ map on the M2 (plus ethanol maps). As much as I love the M2, the engine is still a N55 EWG with minor hardware power mods.
The regular N55 EWG maps are converted to the M2 specific rom and tested as we speak on our DCT M2. The car may yield slightly better result than other EWG N55. So the maps are not shared with the N55 EWG rom, but not very different either.

We aim to become the #1 flash on F like we ware en E series. So yes it's worth it don't worry for us. Plus, I love my M2, which as been the development car for MHD F series.

Just trying to decide between bench and OBD unlock.

No you can't. You can only read the calibration but not the engine program, bootloader etc. But the app can generate a stock file for you (and it uses that system to flash you back to stock without a backup file).

The tamper code was appearing if you did a software update at the dealership, and the boot loader was not overwritten (where the previous unlock patch was written).

Now that we have full obd, we can restore fully the OEM bootloader. Problem solved.

Also one of the other tune groups stated on the forum that you are able to flash the tune to the DME......but to flash back to stock the DME must be removed.

Is that still the case?

Nope no need to remove the DME to flash back to stock (or reinstall MHD).

We'll do that in January. Dynojet are more rare here. I can state our M135i AT was doing a corrected 8.3 to 8.5s 100-200kmh on the 2+ 95oct/102ron map with just DP FMIC. We'll get corrected 100-200 times on the M2 and dynos in January.

Good to hear I will leave the tuning stuff to my friends Matt/John @ EuroMpire/CES

Can the dealer interrogate the DME to see previously higher boost levels, even after flashing back to stock?

I had MHD on my 135i and Loved it!! Smooth as butter... Any Dyno Plots??

That will come end of January for M2.

Not the dealer. But any tune (flash or piggyback) can be seen if BMW (munich) really digs.

In stock form, the M2 targets less rail pressure above 5400 rpm than the 320hp N55s. It also runs a richer AFR. So the M calibration also had to make up with the weak HPFP. It's definitely the limiting factor for 2+, as the car is boost happy. We have to strike a good balance between AFR - rail pressure - boost (remember the jb4 will only affect boost so it has less wiggle room).

Thanks for the response.

Will you be offering the gts style burble, start up and TCU software as an option to like bm3?

great. plan to try this on my stock manual 2017 M2. When will it be read for order?
